Abstract
SE PROVEE UN PROCESO PARA PRODUCIR SULFATO DE POTASIO A PARTIR DE CLORURO DE POTASIO Y ÁCIDO SULFÚRICO. EL PROCESO COMPRENDE MEZCLAR CLORURO DE POTASIO CON AGUA PARA FORMAR UNA SUSPENSIÓN QUE SE MEZCLA CON EL ÁCIDO SULFÚRICO RECICLADO PARA FORMAR UNA MEZCLA DE ÁCIDO K+ , CL- , SO4 2- . ESTA MEZCLA SE SOMETE A UN PROCESO DE CRISTALIZACIÓN QUE PRODUCE CRISTALES DE SULFURO DE POTASIO Y VAPOR DE AGUA-ÁCIDO CLORHÍDRICO. EL ÁCIDO CLORHÍDRICO SE SEPARA PARA FORMAR UNA SOLUCIÓN DE ÁCIDO CLORHÍDRICO.A PROCESS IS PROVIDED TO PRODUCE POTASSIUM SULFATE FROM POTASSIUM CHLORIDE AND SULFURIC ACID. THE PROCESS INCLUDES MIXING POTASSIUM CHLORIDE WITH WATER TO FORM A SUSPENSION THAT MIXES WITH THE RECYCLED SULFURIC ACID TO FORM A K + ACID MIX, CL-, SO4 2-. THIS MIXTURE IS SUBMITTED TO A CRYSTALLIZATION PROCESS THAT PRODUCES POTASSIUM SULFIDE CRYSTALS AND WATER VAPOR-CHLORIDE ACID. THE CHLORIDE ACID SEPARATES TO FORM A CHLORIDE ACID SOLUTION.
